Ianto added: "I was 17 and for the first time, I was able to say my own name without stammering. In the past it would take me up to five minutes just to say it.

"Because my name is Welsh and quite unique, people would ask me to repeat it which would really set the panic in to the point where I couldn’t move. I just clenched my eyes and tried to get my name out.

"Sometimes my jaw would ache because of the amount of tension that I’d be putting on it, trying to pronounce the words. This only made my speech worse.

"Although people might read this and think ‘Okay he said his name, it's no big achievement is it?’ it was a massive achievement and obviously a big deal for me.

"Having to struggle in the past just to say your own name, having the tables turned and saying it without hesitation or struggle, it's a feeling that I’ll never forget.

"I felt like a new man – and I finally had the confidence to meet Hannah."

Ianto met Hannah, 19, from Cardiff, on Twitter four years ago after liking the same band.

"I never thought in a million years I’d be able to ask a girl out, or be able to say my own name in Fixers’ documentary, but here I am."

Hannah, who is at college at Coleg y Cymoedd Nantgarw, said: "When I met Ianto online we began swapping messages and I soon realised we had a lot in common and got on really well.

"When he told me about the speech impediment I wasn’t concerned; I just wanted to do all I could to help. I could tell he lacked confidence because of it.

"I’m not embarrassed if he stutters. I’ll let him speak but I’ll help him out if he needs it.

"I also had my own confidence issues of my own because I’d been in a tough relationship in the past.

"So over time we helped each other out and I’m grateful to him too.

"It’s amazing to see how far he’s come over the years; I’m so proud of him."

And now Ianto has teamed up with Fixers, the charity which helps young people campaign on any issue that matters to them, to make a documentary showing his incredible transformation in a bid to inspire others to overcome speech impediments.

Fixers work with young people across the UK.

Each Fixer is supported by the charity’s team of in-house creative professionals to produce a resource to get their chosen message across.

Many young people choose to create a short film, website, poster campaign or information leaflet, or they hold an event or flashmob.

Fixers has already supported 17,000 young people across the UK to have an authentic voice in their community.

Young people have campaigned on issues with Fixers as diverse as cyber-bullying, self-harm, suicide and the need for more random acts of kindness.

Fixers aims to work with over 70,000 young people aged 16 to 25 by 2020 to help them to take action and tackle the issues they feel strongly about.
